Return Value

Nonzero indicates success. Zero indicates failure. To get extended error information, call GetLastError.


The CheckMenuRadioItem function sets the MFT_RADIOCHECK type flag and the MFS_CHECKED state for the item specified by idCheck and, at the same time, clears both flags for all other items in the group. The checked item is displayed using a bullet bitmap instead of a check mark bitmap.

For more information about menu item type and state flags, see the MENUITEMINFO structure.
